title: Dispersion mapping at the micrometer scale using tri-band optical frequency domain imaging.
abstract: Techniques to differentiate between materials are a powerful addition to the structural information traditionally available from optical coherence tomography images. We present label-free detection of water and lipid at a micrometer scale by evaluating their unique dispersion properties. Using a tri-band swept source configuration, we measure both β(2) and β(3) and show how to identify the two materials at sample thicknesses of 40 and 90 μm, respectively.
